ClinConnect Summary

This clinical trial is studying a medicine called ianalumab to see if giving a second course can help adults with two rare blood conditions: Primary Immune Thrombocytopenia (ITP), where the body attacks its own platelets causing low levels and risk of bleeding, and Warm Autoimmune Hemolytic Anemia (wAIHA), where the body destroys its own red blood cells leading to anemia. The study focuses on people who have already tried ianalumab before and initially benefited from it but later experienced a return or worsening of their condition.

To join the trial, adults 18 years or older must have taken part in earlier ianalumab studies for ITP or wAIHA and had a good response that lasted at least two years before their condition got worse again. Participants may continue to use certain supportive treatments during the study. The trial is not yet recruiting, and those who join will be closely monitored to see if a second treatment with ianalumab is safe and helps control their blood condition again. This study is important because it aims to find better ways to manage these ongoing diseases for people who have already tried this treatment before.

• • Signed informed consent obtained prior to participation in the study.
• • Male or female participants aged 18 years and older on the day of signing informed consent
• Primary ITP patients:
• • Previously enrolled and treated either with ianalumab/placebo in addition to first-line corticosteroids on protocol CVAY736I12301 or with ianalumab/placebo in addition to eltrombopag in the second line on protocol CVAY736Q12301, and who experienced treatment failure (TF) by parent trial definition ≥ 2 years after the last infusion of ianalumab/placebo
• • Rescue medication and/or bridging therapy are allowed to be started within the 28 days prior to screening; platelet count results obtained prior to the start of the therapy must be used to assess eligibility and have to be collected within 30 days prior to screening
• For Primary or secondary wAIHA patients:
• • Previously documented by a positive direct antiglobulin test (DAT) specific for anti-IgG or anti-IgA, previously enrolled and treated with ianalumab/placebo in blinded cohort or placebo followed by crossover to open label ianalumab in protocol CVAY736O12301, having experienced durable response lasting beyond 2 years from the last infusion of ianalumab/placebo in blinded cohorts or a durable response beyond week 20 from last dose of first course of ianalumab in the crossover arm.
• • Relapsed wAIHA with hemoglobin concentration ≥5 g/dL and \<10 g/dL and presence of symptoms related to anemia during screening or within 14 days before screening window or within 28 days before screening window if rescue medication/bridging therapy has been initiated.
• • Rescue medication and/or bridging therapy are allowed to be started during the screening and within 28 days prior to screening; hemoglobin level result for eligibility assessment needs to be obtained prior to the start of the treatment within 30 days prior to screening
• • Supportive care is allowed in the case the participant received it in the parent trial when the relapse occurred and has remained stable at least 4 weeks prior screening
• Exclusion Criteria:
• • Evans syndrome or any cytopenia other than thrombocytopenia (for ITP participants) or anemia (for wAIHA), except for grade 1 anemia due to blood loss or iron deficiency.
• • Secondary wAIHA with BM involvement for wAIHA patients
• • Current life-threatening bleeding or history of life-threatening bleeding due to thrombocytopenia
• • Therapy for ITP or wAIHA other than ianalumab/placebo, bridging/rescue therapies and supportive care prior to the beginning of the screening window
• • After primary analysis of each respective parent trial, participants whose treatment was unblinded and who received placebo only will be excluded.
• • ITP participants only: Participants with concurrent coagulation disorders and/or receiving anti-platelet or anti-coagulant medication except for low dose of acetylsalicylic acid (≤150 mg per day)
• • Other protocol-defined inclusion/exclusion criteria may apply.
